a) complete the table for the 16 x 4 ROM shown and indicate on the diagram how the inputs and outputs are connected to the ROM.
b) Show your K-maps for functions F, G, and H and complete diagram on following page. Note that only 8 product terms are needed.
The Attempt at a Solution
In order to do the truth table, don't you need some sort of functions? In part b it says to k-map functions F G and H. But it doesn't give us an F G or H. And wouldn't there need to be 4 functions for the 4 outputs? And I don't see why only 8 terms would be needed for the diagram either. I can't see how this is possible to even start.
